How do I type French on "QWERTY" keyboard?

I am interested in buying an Ipad Pro with keyboard. My dilemma is I touch type in two languages English and French on a qwerty keyboard. How do I deal with the accents and cedilla using the qwerty?
I know people say use the French keyboard but anyone touch typing will know this is not an option.
Are there any special characters that can be used?
Once upon a time one could press the "alt" key and use a combination of figures with the number pad. Has Apple taken this into consideration?
Many thanks for your help.
